Diagnose Slow Dryer Cycles With a Vent Inspection

Cost Savings

Checklist Tasks

• Unplug the dryer and move it away from the wall to access the vent safely.
• Detach the vent hose and check both ends for lint blocking airflow.
• Shine a flashlight into the wall vent to spot lint clumps or animal nests.
• Run a flexible brush or vacuum through the vent duct to clear compacted debris.
• Inspect the exterior vent hood for stuck flaps or animal nests impeding airflow.
• Check for kinks or crushed vent hose sections that restrict air movement.
• Feel along the vent duct while running to detect leaks or loose joints.
• Ensure the vent hose is as short and straight as possible to limit lint traps.
• Clean the lint filter slot with a vacuum nozzle to remove hidden lint buildup.
• Test the dryer with a full load and time the cycle for improved drying speed.
• Listen for rattling or whistling noises indicating loose or damaged vent joints.
• Seal vent joints with foil tape to prevent leaks and keep lint contained.
